BUTTERr-PAT-IVIAKIN'G MACHINE.

To all whom it may concern Be it known that I, GEORGE WV. FURBEUK, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Butter-Pat- Making Machines, of which the following is a specification.

This invention relates to butter-pat making machines, and has for its object to produce a machine of this character by which a block of butter can be rapidly converted into rectangular pats of uniform size and by which the pats are separated from the block and each other as completed.

Another object is to produce a machine having a cam-wheel for alternately effecting the advance of the block of butter from which the pats are to be made and the operation of a slicer to complete the formation of and separate the pats from the block of butter.

A further object is to produce a machine of this character of simple, durable and cheap construction.

With these objects in view, the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described andclaimed; and in order that it may be clearly understood reference is to be had to the accompanying drawings, in which:

Figure 1, is a side elevation of a butterpat making machine embodying my invention. Fig. 2, is a top plan "view of the same. Fig. 3, is a front view of the same. Fig. 4, is a vertical section on the line IV1V of Fig. 2, with the pl'esser-plate in its most advanced position. Fig. 5, is an enlarged vertical section on the line V-V of Fig. l. Fi 6, is a fragmentary perspective view of the rack-bar of the machine.

In the said drawings, where like reference characters identify corresponding parts, 1 indicates a U-shaped butter holder or receptacle open at each end and having one of its side walls extended rearwardly at 2, and said holder and its extended wall is mounted on legs 3. At its front end the receptacle is bridged by a cross bar 4, and is flanked by a pair of vertical bars 5, which project to a lower plane than the bottom of the receptacle and to a higher plane than said cross bar, and constitute guides for the slicer, as hereinafter explained.

.6 are crossed wires extending from side to Specification of Letters Patent.

side of the receptacle and from the bottom thereof to the bridge bar at, these crossed wires constituting stationary cutters for kerfing the butter preliminary to the operation of the slicer.

7 is a presser plate corresponding in form and adapted to lit snugly in the holder and almost in contact when in its most advanced position with the bridge bar l, and said plate is provided at its front side with crossed grooves S to receive the crossed cutters 6, during the operation of the slicer. The prcsser plate is secured to the front end of an angle bar t) fitting against the wall of the holder provided with the extension 9., and said angle bar is provided with a pair of pins 1.0 and a clamping screw 11.

12 is a rack-bar fitting against bar S) and provided with holes 13 receiving pins 10, and with a notch 14; in its lower edge, receiving the clamping screw 11. When the clamping screw is removed the rack-bar can be slipped oil the pins but cannot become dislodged therefrom while the clamping screw remains in position. The raclebar is made detachable so that it may be replaced by another one having teeth of different length, in order that the pats of butter may be of the desired thickness, as the length of the teeth determines the thickness of the pats.

\Vhen the prcsser plate is in its most advanced position, as shown in Fig. 4, it can be tilted slightly and then lifted out of the receptacle, as at such time the angle bar 9 is forward of a retaining pin 14; projecting inwardly from the extension When the presser plate is withdrawn a distance cor responding to the length of a tooth or two, the rear end of the angle bar underlies pin 1* and at the same time said angle bar, for the purpose of holding the prcsscr plate vertical, rests upon a channeled track bar 15 secured to extension 2, the said extension and the portion of the bar 15 which overlaps the side of the angle bar, guarding against any possibility of movement of the bar S) whereby its support upon the track would be endangered.

Secured to and at the inner side of the extension 2, and lying wholly above the plane of the raek-bar, is a casting ll), and secured to said casting are caps 17 supporting a longitudimilly-movable bar 18 and pivoted to the front end of said bar 18 for movement in a vertical plane, is a pawl 19 resting upon the rack-bar. Journaled at the rear end of the extension 2, and at the upper end of the rear leg 3, is a cam-wheel 20, provided with an operating handle 21 and an oval shaped cam-groove, and said groove receives a small anti-friction roller 21 journaled on the rear end of barlS, the arrangement'being such that in each revolution of the cam wheel, the bar 18 is reciprocated to cause the pawl to advance and withdraw, and in its advance movement, by engagement with a tooth of the rack-bar, advance the presser plate one step, the withdrawal movement of the pawl disposing its front end rearward of the next tooth of the rack-bar. The parts are so proportioned that less than a quarter revolution of the cam wheel causes the presser plate to advance one step. As arranged this step begins shortly after the handle starts forward from a vertically pendent position and terminates as said handle attains a forwardly-projecting horizontal position.

Assuming that the receptacle or holder is proportioned to snugly receive a pound of butter in the form of a block, as customary, and that it is placed in the holder with the presser plate engaging its rear end, and extends from said presser plate to the crossed cutters 6, it will be seen that advance movement of the presser plate causes the block of butter to advance a corresponding distance, and that the said crossed cutters will produce crossed orint'ersecting kerfs in the butter' to a depth corresponding to the length of a toot-h of the rack-bar, and that the kerfed portion projects beyond the front end of the holder.

In order to slice the projecting kerfed portion from the block of butter, I provide the' following construct-ion: 24 is a rock-lever pivoted to the casting 16, and journaled on the rear end of said lever is a roller 25 engaging the groove 22 of the cam wheel. At its front end the rock-lever is equipped with a pair of angle arms 26 and 27 and pivoted upon a cross-rod 28 carried by said angle arms, is an inverted U-shaped frame 29, the arms of said frame being connected near their lower ends by a cross wire or slicer 30, which bears slidingly against the front edges of the guide bars 5 just forward of V the plane of the stationary cutters 6. Mounted on pivot rod 28 is a coiled spring'31 bearing at one extremity at 82 on angle bracket- 27 and at the other extremity on the bridge or top bar of the inverted U- lateral movement of the slicer frame in the end of the block of butter The slicer 30 may be secured in place 7 event that a person handles the machine carelessly, as without guarding against undue lateral movement, the rock lever might be bent or distorted. With each revolution of the cam-wheel the rock-lever depresses and reelevates the slicing frame 29, the sheer 30 thereof moving vertically because of the guide bars 5, it being also apparent that the frame 29 will have a slight pivotal movelever as the latter moves upward. As the parts are proportioned the slicing frame 1 starts downward at about the instant the thus completes the formation of four complete pats and separates them from the block of butter and from each other, the said holder upon a table or into a receptacle placed to receive them. 7

From the above description it will be apparent that I have produced a butter-pat making machine embodying the features of pats dropping at the front end of the advantage enumerated as desirable, and I wish it to be understood that I reserve the right to make such changes in the form, proportion, detail construction and 'organiza- 7 tion of the parts as properly fall within the principle of construction defined by the appended claims. I
